一,Lense ea UV ke eng
Lense ea UV, eo hape e tsejoang e le lense ea ultraviolet, ke lense ea optical e etselitsoeng ka ho khetheha ho fetisa le ho tsepamisa leseli la ultraviolet (UV). Leseli la UV, le bolelele ba maqhubu a maqhubu a pakeng tsa 10 nm ho ea ho 400 nm, le ka nqane ho mefuta e mengata ea leseli le bonahalang holim'a mabone a motlakase.
Lilense tsa UV li sebelisoa hangata lits'ebetsong tse hlokang ho nahana le ho hlahlojoa ka har'a mefuta ea UV, joalo ka microscope ea fluorescence, spectroscopy ea UV, lithography le likhokahano tsa UV. Lilense tsena li khona ho fetisa leseli la UV ka ho monya ho fokolang le ho hasana, ho lumella ho nka litšoantšo tse hlakileng le tse nepahetseng kapa tlhahlobo ea lisampole kapa lintho.
Moralo le ho etsoa ha lilense tsa UV li fapane le tsa lilense tse bonahalang tsa khanya ka lebaka la litšobotsi tse ikhethang tsa lebone la UV. Lisebelisoa tse sebelisoang bakeng sa lilense tsa UV hangata li kenyelletsa silica e kopantsoeng, calcium fluoride (CaF2), le magnesium fluoride (MgF2). Lisebelisoa tsena li na le phetisetso e phahameng ea UV le ho monya ha UV e tlase, e li etsang hore li tšoanelehe bakeng sa lits'ebetso tsa UV. Ntle le moo, moralo oa lense o hloka ho nahana ka likhalase tse khethehileng tsa optical ho ntlafatsa phetiso ea UV.
Lilense tsa UV li tla ka mefuta e fapaneng, ho kenyelletsa le lilense tsa plano-convex, biconvex, convex-concave le meniscus. Khetho ea mofuta oa lense le litlhaloso li ipapisitse le litlhoko tse ikhethileng tsa ts'ebeliso, joalo ka bolelele bo lakatsehang, sebaka sa pono, le boleng ba setšoantšo.
二、Te na le likarolo le ts'ebeliso ea lilense tsa UV
Ho na le likarolo le ts'ebeliso ea lilense tsa UV:
Flijo:
Phetiso ea UV: Lilense tsa UV li etselitsoe ho fetisa leseli la ultraviolet ka ho monya ho fokolang le ho hasana. Li na le phetisetso e phahameng ho leqhubu la maqhubu a UV, hangata lipakeng tsa 200 nm ho isa ho 400 nm.
Aberration e tlase: Lilense tsa UV li etselitsoe ho fokotsa ho kheloha ha chromatic le mefuta e meng ea ho sotha ha mahlo ho netefatsa sebopeho se nepahetseng sa setšoantšo le tlhahlobo ho mefuta ea UV.
Khetho ea Lintho:Lilense tsa UV li entsoe ka thepa e nang le phetisetso e phahameng ea UV le ho monya ha UV e tlase, joalo ka silika e kopantsoeng, calcium fluoride (CaF2), le magnesium fluoride (MgF2).
Liaparo tse khethehileng: Hangata lilense tsa UV li hloka liphahlo tse khethehileng tsa mahlo ho ntlafatsa phetiso ea UV, ho fokotsa likhahla le ho sireletsa lense ho tsoa linthong tsa tikoloho.
Lisebelisoa:
Setšoantšo sa Fluorescence Microscopy:Hangata lilense tsa UV li sebelisoa ho microscopy ea fluorescence ho hlasimolla le ho bokella mats'oao a fluorescent a hlahisoang ke fluorophores. Mohloli oa leseli la UV o thusa ho hlasimolla li-probes tse khethehileng tsa fluorescent, tse lumellang ho nka litšoantšo ka botlalo tsa disampole tsa baeloji.
UV Spectroscopy:Lilense tsa UV li sebelisoa lits'ebetsong tsa spectroscopy tse hlokang tlhahlobo ea ho monya ha UV, ho tsoa, kapa ponahalo ea phetiso. Sena se bohlokoa mafapheng a fapaneng a lipatlisiso tsa mahlale, ho kenyeletsoa k'hemistri, tlhahlobo ea tikoloho, le mahlale a thepa.
Lithography:Lilense tsa UV ke likarolo tsa bohlokoa ho photolithography, mokhoa o sebelisoang ho etsa semiconductor ho hatisa lipaterone tse rarahaneng holim'a li-wafers tsa silicon. Ho pepesetsoa ha leseli la UV ka lense ho thusa ho fetisetsa lipaterone tse nang le lintlha tse ngata ho lisebelisoa tsa photoresist.
Lipuisano tsa UV:Lilense tsa UV li sebelisoa lits'ebetsong tsa puisano tsa UV bakeng sa phetiso ea data e se nang mohala ea nako e khuts'oane. Leseli la UV le nolofalletsa puisano ea pono, hangata lits'ebetsong tsa kantle, moo litšitiso tse kang lifate le meaho li nang le tšitiso e nyane ha li bapisoa le khanya e bonahalang.
Forensics le Document Analysis:Lilense tsa UV li sebelisoa tlhahlobo ea forensic le tlhahlobo ea litokomane ho senola tlhahisoleseling e patiloeng kapa e fetotsoeng. Leseli la UV le ka sibolla lintho tse sebetsang ka UV, la senola likarolo tsa ts'ireletso, kapa la bona litokomane tse qotsitsoeng.
Ho senya UV:Lilense tsa UV li sebelisoa lisebelisoa tse thibelang likokoana-hloko tsa UV ho bolaea likokoana-hloko metsing, moea kapa bokaholimo. Leseli la UV le hlahisoang ka lense le sebetsa haholo ho fokotseng DNA ea likokoana-hloko, e leng se etsang hore e be khetho e tsebahalang bakeng sa ho hloekisa metsi le ho thibela likokoana-hloko.
Ka kakaretso, lilense tsa UV li fumana ts'ebetso mefuteng e mengata e fapaneng ea mahlale, indasteri le thekenoloji moo litšoantšo tse nepahetseng tsa UV, tlhahlobo ea pono kapa ho thetsoa ha leseli la UV ho leng bohlokoa.
